Self-employment professionals issue a self-employment receipt instead of an invoice. e-SMM is the electronic version of this document and is now the standard practice for a wide range of professionals.
In this article, we explained the timing of issuing e-SMM, its withholding tax and VAT structure, and how it should be recorded on the business side.

What is e-SMM?
A self-employment receipt is the record documenting the amount collected in exchange for self-employment activities. e-SMM is its electronically issued, signed, and stored version.
The main difference from an invoice is that the issuer generates self-employment income rather than commercial profit. This directly affects the taxation structure.
The document constitutes an expense for the service recipient and income for the service provider. Both parties' records must match each other.
When is it issued?
The core principle in self-employment income is cash basis collection. The receipt is generally issued at the moment the fee is collected, even if the service was rendered months ago.
This is a different logic from commercial invoices. For invoices, the moment of delivery or service is decisive; for receipts, money movement is decisive.
In partial collections, a separate receipt is issued for each collection. For long-term consultations, this turns into a recurring task on a monthly basis; we covered a similar setup in the recurring service invoices article.
From gross to net: calculation structure
In e-SMM, three items are calculated together: gross amount, income tax withholding, and VAT. This trio can be confusing for those seeing the document for the first time.
Withholding tax is deducted over the gross amount; this is the responsibility of the service-receiving party. VAT, on the other hand, is calculated over the gross amount and is not affected by withholding.
Consequently, the amount paid to the self-employment professional and the total of the document are different from each other. Misunderstandings often occur because parties frequently discuss different figures.
In some cases, VAT withholding may also come into play. Rates and withholding practices vary; confirm with your financial advisor.
What does the receiving party do?
If you are on the business side, e-SMM is an expense document for you and lands in your incoming document inbox. Like other documents, it needs to be processed regularly.
The withholding responsibility lies with you. Forgetting to declare withholding after receiving the receipt and making the net payment is a situation that requires subsequent correction.
The habit of scanning incoming documents daily prevents such oversights. We covered this routine in the incoming document inbox management article.
Payment records must also match the receipt. You can check the bank integration and rule engine article to correctly link bank statement transactions to the right account.
Expense entry and cost center
Self-employment services typically belong to a specific project or department. Legal consulting is tied to a lawsuit, while architectural services are tied to a construction site.
Recording these expenses on a cost center or project basis enables subsequent cost analysis. Otherwise, all consulting expenses are lumped into a single item and lose their meaning.
We explained this structure in the cost center-based expense tracking and project definitions articles.
Defining service items as cards also simplifies the process. The service and expense module keeps non-stock items in a separate structure.
A well-organized bookkeeping routine
If you are a self-employment professional, the number of receipts you need to issue might not be high; however, disorganization creates a backlog of work at the end of the month.
A practical suggestion is to record the collection and issue the receipt at the same time. If the document is issued as soon as the money hits the account, there is no need for retrospective recollection.
Client-based tracking is also important. It should be visible how much collection was made from which client and which job's payment is pending; the cash flow tracking article addresses this visibility.
The obligation to store documents applies here as well; you can check the e-document archiving article.
Collection tracking and client communication
For self-employment professionals, collection is particularly critical because it determines the moment the receipt is issued. A service that has not been collected is also considered incomplete in terms of accounting.
Therefore, it should be clear which job's payment is pending. A list of completed but uncollected jobs is a screen that needs to be reviewed regularly.
Tools that facilitate collections come in handy here as well. Sending a payment link yields much faster results than sharing an IBAN and waiting; you can check the payment link article.
For long-term consultations, it is beneficial to establish a periodic billing routine. Automated reminders at the end of the month both organize collections and make cash flow predictable.
Keeping records of meetings with clients also makes things easier; you can be asked months later what was discussed for which task. Check out the Customer 360 view article.
Digital order for small offices
Most self-employment professionals work with small teams. At this scale, setting up a heavy system is not necessary; however, a basic routine makes a huge difference.
Having three things recorded is sufficient: client cards, issued receipts, and expenses. When these three are kept together, end-of-period preparation takes minutes instead of hours.
The expense side is particularly neglected. When office rent, software subscriptions, and professional expenses are not recorded regularly, they cannot be gathered at the end of the period; you can look at the service and expense definitions article.
If you work on a project basis, linking income and expenses to the project shows which job is truly profitable; check out the project definitions article.
Enabling only the modules you need during setup keeps costs low; modular licensing provides this flexibility.
Frequently asked questions
Can a receipt be issued without collection?
The general rule is the cash basis. Consult your financial advisor for exceptional cases.
Who pays the withholding tax?
The service-receiving party deducts and declares it. The self-employment professional offsets this amount in their annual return.
Is there withholding on receipts issued to end consumers?
Withholding responsibility generally arises for those holding the status of tax responsible parties. Clarify this with your financial advisor based on your situation.
Can a receipt be cancelled?
Electronic document correction rules apply; check out the cancellation and objection article.
e-SMM is a record that ties the collection to the document issuance at the same moment. When this connection is established, both declarations and client tracking naturally fall into order.
By consulting with the EQLEM team, you can discuss how to manage your service documents along with collection and expense tracking.
